Single-probe online density measurement method and online densimeter

Abstract

The invention discloses a single-probe online density measurement method and an online densimeter, and relates to the technical field of online densimeters. The device comprises a main pipeline, a detection probe and a mounting shell, a measurement main body is mounted above the main pipeline, a display screen is arranged in the middle of the measurement main body, and an upper guide pipe is fixed at the lower end of the measurement main body; a mounting flange is installed below the upper guide pipe, a fixing bolt is arranged on the outer side of the mounting flange, a connecting pipe is fixed to the lower end of the upper guide pipe, a sealing ring is arranged on the outer side of the connecting pipe, the detection probe is installed below the connecting pipe, and pressure repeaters are arranged below the detection probe. A temperature sensor is fixed between the pressure repeaters, and the mounting shell is arranged on the outer side of the lower part of the mounting flange. The beneficial effects are that the device can achieve the buffering and damping effects through the arrangement of the damping base and the buffering spring in the damping base, enables the setting of the measurement main body to be stable, and reduces the impact on the measurement result from the environmental factor.

Description

technical field [0001] The invention relates to the technical field of online densitometers, in particular to a single-probe online density measurement method and an online densitometer. Background technique [0002] Intelligent online density meter (also known as online density transmitter) is a device for continuous online measurement of the concentration and density of liquids, which can be directly used in industrial production processes. The density meter adopts advanced technology, and the intelligent online density meter is a two-wire density transmitter, which is mainly used for industrial process control, and can be remotely calibrated and monitored through digital communication. [0003] The existing online density meter is not well sealed when it is connected to the pipeline, and it cannot be installed vertically and stably. It may be skewed and affect the detection structure, and it does not have the function of buffering and shock absorption, and the use effect ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a single-probe online density measurement method and an online density meter to solve the problem that the existing online density meter proposed in the background art has insufficient sealing at the joint when it is connected to the pipeline and cannot be vertically Straight and stable setting, there may be a skewed situation that affects the detection structure, and it does not have the effect of cushioning and shock absorption, and the use effect is not good.
